The problem stays (I am now on a second machine, but same system Debian
unstable).
After stripping off the compiler options, the command line is
x86_64-w64-mingw32-gcc-win32 -DHAVE_CONFIG_H -I. -I..
-I/home/tim/src/wget2/x86_64-w64-mingw32/include -no-integrated-cpp
-DNDEBUG -fno-PIC -MT fatal-signal.lo -MD -MP -MF .deps/fatal-
signal.Tpo -c fatal-signal.c -DDLL_EXPORT -DPIC -o .libs/fatal-
signal.o
In the -E output there is
# 593 "./signal.h" 3
extern int 0
;
Line #593-594 in signal.h is:
_GL_FUNCDECL_SYS (pthread_sigmask, int,
(int how, const sigset_t *new_mask, sigset_t
*old_mask));
I am using glthreads.
Maybe that has to do with the configure flag --disable-threads !?
The glthread functions are defined a 0 in this case.
The surrounding code in signal.h looks like
#if 1
# if 0
# if !(defined __cplusplus && defined GNULIB_NAMESPACE)
# undef pthread_sigmask
# define pthread_sigmask rpl_pthread_sigmask
# endif
_GL_FUNCDECL_RPL (pthread_sigmask, int,
(int how, const sigset_t *new_mask, sigset_t
*old_mask));
_GL_CXXALIAS_RPL (pthread_sigmask, int,
(int how, const sigset_t *new_mask, sigset_t
*old_mask));
# else
# if !0
_GL_FUNCDECL_SYS (pthread_sigmask, int,
(int how, const sigset_t *new_mask, sigset_t
*old_mask));
# endif
...
Any more ideas / hints ?
